Description

Technical Field

[0001] The invention relates to the technical field of printing devices, and in particular to a digital printing device with a bottle clamping and rotating mechanism. Background Art

[0002] Printing is a common technology. It is a technology that transfers the ink of text, pictures, photos, anti-counterfeiting manuscripts to the surface of paper, textiles, plastics, leather, PVC, PC and other materials through plate making, inking, pressurization and other processes to batch copy the original content. There are many ways to print, among which digital printing is one of the many printing methods. Digital printing is a way of printing using digital technology. It breaks the limitations of traditional printing and directly converts electronic files into physical prints without going through complicated processes such as plate making and plate repair. It has the advantages of high efficiency, convenience, environmental protection and energy saving, flexibility and high definition. Digital printing has been widely used in many fields due to its unique advantages. Among them, in the printing of some packaging bottles, digital printing is also often used to print product names, promotional patterns, detailed information, etc. on the packaging bottles.

[0016] 1. The servo motor drives the reciprocating screw to rotate, so that the reciprocating block reciprocates, driving the nozzle to reciprocate, and one reciprocating cycle performs one printing. After one printing, the reciprocating block contacts the rack at the right block, and the rack meshes with the third gear, so that the clamped packaging bottle rotates, so that the packaging bottle can be printed at different positions during the next printing, so that multiple positions of the packaging bottle can be printed at one time, which greatly improves the printing efficiency and reduces the equipment cost;

After adjusting the printing on different surfaces, the printed packaging bottles will also be rotated at the same angle, so that the different printed surfaces of the printed packaging bottles can face the first tube. No matter how the printing surface is adjusted, the printing surface can be guaranteed to face the first tube for ink drying, so that no matter how the printing surface is adjusted, good drying of the printing ink can be guaranteed.

[0032] The main body 2 is provided with a driving mechanism, which includes a hollow left block 13 and a right block 14. The left block 13 and the right block 14 are both fixedly connected to the side wall of the main body 2. The bottom walls of the left block 13 and the right block 14 are penetrated and fixedly connected with a second tube 21. The side walls of the left block 13 and the right block 14 on the opposite side are penetrated and slidably connected with a rack 15. The left block 13 and the right block 14 are sealed and slidably connected with a piston plate 16. The rack 15 is fixedly connected to the corresponding side wall of the piston plate 16. The piston plate 16 A plurality of first springs 17 are fixedly connected to the inner side walls of the corresponding left block 13 or right block 14. The left block 13 and the main body 2 are rotatably connected to a main shaft 18 through a bearing. The right block 14 and the main body 2 are rotatably connected to a secondary shaft 19 through a bearing. One end of the main shaft 18 and the secondary shaft 19 located in the left block 13 and the right block 14 are rotatably connected to a third gear 20 through a one-way bearing. The one-way bearings between the main shaft 18, the secondary shaft 19 and the third gear 20 allow for opposite rotation directions.

[0033] The drive mechanism also includes a secondary pulley 36 (such as Figure 7 As shown, the secondary pulley 36 is fixedly connected to the first tube 8 through the bearing, and the end of the main shaft 18 located in the main body 2 is rotatably connected to the electric clutch 34 through the bearing. The electric clutch 34 can be combined with the main shaft 18 after power is turned on, and disconnected from the main shaft 18 after power is turned off. The electric clutch 34 and the secondary shaft 19 are both fixedly connected to the main pulley 35 through the bearing, and the main pulley 35 and the secondary pulley 36 are jointly equipped with a synchronous belt 37. The turntable 9 is rotatably connected to multiple side shafts 10 through a one-way bearing, and the side shaft 10 is fixedly connected to the second gear 12 at one end inside the main body 2. The first tube 8 is penetrated A first gear 11 is fixedly connected, the first gear 11 is meshed with the second gear 12, and a one-way bearing is set between the side shaft 10 and the turntable 9. When the main shaft 18 rotates to make the first tube 8 rotate and drive the first gear 11 to rotate, the first gear 11 rotates to drive the second gear 12 to rotate, and the second gear 12 drives the side shaft 10 to rotate. The side shaft 10 cannot rotate at this time, so that the entire turntable 9 rotates. At this time, the first gear 11 and the second gear 12 are in a clamping state, but not in a meshing state. When the secondary shaft 19 rotates, the side shaft 10 can rotate the rod, so that the clamped The packaging bottle rotates, the servo motor 3 rotates to drive the reciprocating screw 4 to rotate, and the reciprocating screw 4 rotates to drive the reciprocating block 6 to reciprocate. During the movement of the reciprocating block 6 toward the secondary shaft 19, the printing ink is sprayed and printed on the packaging bottle. After the reciprocating block 6 is printed, it continues to move toward the secondary shaft 19, and the rack 15 drives the piston plate 16 to move. The rack 15 is engaged with the third gear 20, and the rack 15 drives the third gear 20 to rotate, so that the secondary shaft 19 rotates. The rotation of the secondary shaft 19 drives the main pulley 35 to rotate, and the main pulley 35 drives the secondary shaft 19 through the synchronous belt 37. The pulley 36 rotates, and the secondary pulley 36 drives the first tube 8 to rotate, thereby causing the first gear 11 to rotate. The rotation of the first gear 11 drives the second gear 12 meshing therewith to rotate, and the second gear 12 drives the side shaft 10 to rotate. At this time, due to the setting of the one-way bearing, the side shaft 10 can rotate at this time, thereby rotating the clamped packaging bottle by a certain angle, and then the reciprocating block 6 changes the direction of movement. When printing next time, different positions of the packaging bottle can be printed, so that multiple positions of the packaging bottle can be printed at one time, which greatly improves the printing efficiency and reduces the equipment cost.

[0034] The left block 13 and the right block 14 are provided with a control mechanism, which includes a functional cylinder 24 (such as Figure 4As shown in the figure, the function cylinder 24 is fixedly connected to the upper surface of the right block 14, and a trigger block 26 is sealed and slidably connected inside the function cylinder 24. A second spring 27 is fixedly connected between the trigger block 26 and the inner top wall of the function cylinder 24. A hole (not shown in the figure) is opened on the top wall of the function cylinder 24, so that the part of the function cylinder 24 located above the trigger block 26 is connected to the outside world, thereby ensuring that the sealed sliding trigger block 26 can slide freely in the function cylinder 24. A delay switch 28 is fixedly connected to the inner top wall of the function cylinder 24, and the top wall of the right block 14 A third tube 25 is fixedly connected through the tube, and the third tube 25 connects the right block 14 with the functional cylinder 24. A fourth tube 29 is fixedly connected through the side wall of the functional cylinder 24, and the fourth tube 29 connects the functional cylinder 24 with the outside. A solenoid valve 30 is arranged in the fourth tube 29. The solenoid valve 30 is a normally closed solenoid valve, which can be opened by power-on. The solenoid valve 30, the electric clutch 34 and the delay switch 28 are electrically connected through wires. After the delay switch 28 is pressed, the solenoid valve 30 and the electric clutch 34 can be energized for a certain period of time, and then the power is automatically cut off.

[0035] It should be noted that the amount of air pumped into the functional cylinder 24 each time the piston plate 16 in the right block 14 moves is related to the rotation angle of the clamped packaging bottle, and the amount of air required for the trigger block 26 to slide up and contact the delay switch 28 is just enough to make the clamped packaging bottle rotate one circle, so that no matter how much the rotation angle and the number of printing times are, the trigger block 26 can contact the delay switch 28 after the clamped packaging bottle rotates one circle.

[0036] The control mechanism also includes a threaded barrel 31, which is rotatably connected to the side wall of the right block 14 through a bearing, and a screw 32 is threadedly connected to the threaded barrel 31. A top plate 33 is slidably connected between the two opposite inner side walls of the right block 14, and the top plate 33 is fixedly connected to the screw 32. The reciprocating block 6 is provided with a sliding groove 38, and the reciprocating block 6 is slidably connected to a moving block 39 through the sliding groove 38. A third spring 40 is fixedly connected between the moving block 39 and the inner side wall of the sliding groove 38. The stiffness coefficient of the third spring 40 is greater than that of the first spring 17, so that After the moving block 39 contacts the rack 15 at the right block 14, the rack 15 first drives the piston plate 16 in the right block 14 to move, until the piston plate 16 cannot move, the moving block 39 starts to move. After multiple printings are completed, the moving block 39 moves and contacts the rack 15 at the right block 14, and drives the clamped packaging bottle to rotate again. At this time, the trigger block 26 rises and contacts the delay switch 28, and triggers the delay switch 28, so that the solenoid valve 30 is energized. Under the elastic force of the second spring 27, the trigger block 26 is reset, and the electric clutch is engaged. 34 is energized synchronously, at this time, the reciprocating block 6 continues to change the direction of movement, and contacts the rack 15 of the left block 13 and pushes it, the rack 15 drives the third gear 20 to rotate, the rotation of the third gear 20 drives the main shaft 18 to rotate, and because the electric clutch 34 is energized at this time, the main shaft 18 will drive the corresponding main pulley 35 to rotate, the main pulley 35 drives the secondary pulley 36 to rotate through the synchronous belt 37, the rotation of the secondary pulley 36 drives the first tube 8 to rotate, so that the first gear 11 rotates, and due to the setting of the one-way bearing, the first gear 11 rotates Then the second gear 12 cannot be driven to rotate. At this time, the rotation of the first tube 8 will drive the entire turntable 9 to rotate, and drive all the packaging bottles to revolve, so that the printed packaging bottle rotates away from under the nozzle 7, and the next packaging bottle rotates to under the nozzle 7 to wait for printing. After the printing of one packaging bottle is completed, the entire turntable 9 rotates, driving all the packaging bottles to revolve, the printed packaging bottle rotates away from under the nozzle 7, and the next packaging bottle to be printed is rotated to under the nozzle 7, thereby completing automatic loading, greatly improving the automation level of the device.

[0037] It is worth mentioning that after adjusting the printing on different surfaces, the printed packaging bottle will also be rotated at the same angle, so that the different printed surfaces of the printed packaging bottle can face the first tube 8. No matter how the printing surface is adjusted, the printing surface can be guaranteed to face the first tube 8 for ink drying, so that no matter how the printing surface is adjusted, good drying of the printing ink can be guaranteed.

[0038] The turntable 9 is provided with a bottle clamping mechanism, which includes a plurality of conductive blocks 45, which are fixedly embedded in the side wall of the turntable 9, and the conductive blocks 45 correspond to the side shafts 10 one by one. The main body 2 is fixedly embedded with a conductive ring 44, and one end of the side shaft 10 located outside the main body 2 is fixedly connected with a frame 41, and the frame 41 is penetrated and fixedly connected with two electric push rods 42, which are electromagnetic push rods, which extend when powered on and retract when powered off, and the output end of the electric push rod 42 is fixedly connected with a clamping block 43, and the electric push rod 42, the conductive block 45, and the conductive ring 44 are electrically connected through a wire, and the arrangement of the conductive ring 44 and the conductive block 45 is as shown in the figure. Figure 5 As shown, the conductive ring 44 is not a complete ring, but has a certain gap. When the conductive block 45 contacts the conductive ring 44, the corresponding electric push rod 42 will be energized and extended. When the conductive block 45 separates from the conductive ring 44, the corresponding electric push rod 42 will be de-energized and retracted.

[0039] A through block 47 is fixedly connected to the side wall of the main body 2. The through block 47 is a hollow structure. The through block 47 and the left block 13 are penetrated and fixedly connected with a fifth tube 46. The first tube 8 is rotatably connected to the through block 47 through a bearing. A plurality of sixth tubes 48 are penetrated and fixedly connected to the side wall of a section of the first tube 8 located outside the main body 2. When the reciprocating block 6 moves toward the main shaft 18, it drives the movement of the piston plate 16 in the left block 13, pumps the air in the left block 13 into the through block 47 through the fifth tube 46, and then enters the first tube 8, and is discharged through the sixth tube 48 and blown toward the printed packaging bottle, thereby increasing the air flow rate and drying the printing ink.

[0040] One-way valves are provided in the second tube 21, the third tube 25 and the sixth tube 48. The one-way valve in the second tube 21 only allows external air to enter the left block 13 and the right block 14. The one-way valve in the third tube 25 only allows air to enter the functional cylinder 24 from the right block 14. The one-way valve in the sixth tube 48 only allows air to enter the through block 47 from the left block 13.

[0041] A pointer (not shown) is fixedly connected to the side wall of the threaded barrel 31, and a scale line (not shown) is engraved on the side wall of the right block 14 away from the reciprocating block 6. The position of the top plate 33 can be accurately adjusted by the pointer and the scale line, thereby accurately adjusting the movement distance of the piston plate 16 located in the right block 14, and then accurately adjusting the rotation angle of the clamped packaging bottle, thereby ensuring the accuracy of the printing position. A guide block 49 is fixedly connected to the upper surface of the base 1, and the upper surface of the guide block 49 is an arc surface (such as Figure 1 As shown), a rubber pad is glued to the upper surface of the guide block 49, so that the fallen packaging bottle can fall along the guide block 49, and the rubber pad can increase the cushioning of the fall to avoid damage to the packaging bottle.

[0042] In the present invention, firstly, the threaded barrel 31 is rotated according to the required rotation angle of the packaging bottle and the number of printing times, and the position of the top plate 33 is adjusted through the threaded connection between the threaded barrel 31 and the screw rod 32. The position of the top plate 33 is accurately adjusted according to the pointer and the scale line on the threaded barrel 31, and the packaging bottle is placed between the two clamping blocks 43. The conductive block 45 contacts the conductive ring 44, so that the electric push rod 42 is energized and extended, and the packaging bottle is clamped by the clamping block 43.

[0043] The rotation of the servo motor 3 drives the reciprocating screw 4 to rotate, and the rotation of the reciprocating screw 4 drives the reciprocating block 6 to reciprocate. During the movement of the reciprocating block 6 toward the direction of the secondary shaft 19, the printing ink is sprayed and printed on the packaging bottle. After the reciprocating block 6 completes printing, it continues to move toward the secondary shaft 19, so that the moving block 39 contacts the rack 15 at the right block 14, and drives the piston plate 16 in the right block 14 to move through the rack 15. The movement of the piston plate 16 pumps the air in the right block 14 into the functional cylinder 24, so that the trigger block 26 moves upward for a distance. At the same time, the rack 15 meshes with the third gear 20, and the rack 15 drives the third gear 20 to rotate, thereby rotating the secondary shaft 19. The rotation of the secondary shaft 19 drives the main pulley 35 to rotate, and the main pulley 35 drives the secondary pulley 36 to rotate through the synchronous belt 37. The rotation of the secondary pulley 36 drives the first tube 8 to rotate The second gear 12 meshing with the first gear 11 rotates, and the second gear 12 drives the side shaft 10 to rotate. At this time, due to the setting of the one-way bearing, the side shaft 10 can rotate at this time, thereby rotating the clamped packaging bottle by a certain angle, until the piston plate 16 in the right block 14 contacts the top plate 33 and cannot continue to move, but makes the moving block 39 slide into the sliding groove 38, and then the reciprocating block 6 changes the direction of movement, and the piston plate 16 in the right block 14 is reset under the elastic force of the first spring 17, and the outside air is drawn into the right block 14 through the second tube 21. At the same time, the piston plate 16 in the right block 14 drives the rack 15 to reset, and due to the setting of the one-way bearing, when the rack 15 is meshed with the third gear 20 when resetting, the rotation of the third gear 20 will not drive the secondary shaft 19 to rotate.

[0044] After the reciprocating block 6 changes its direction of movement, it continues to move and contacts the rack 15 at the left block 13, and pushes the rack 15 to move. At this time, the third gear 20 meshing with the rack 15 rotates, and the rotation of the third gear 20 drives the main shaft 18 to rotate. At this time, since the electric clutch 34 is not energized, the main shaft 18 will not drive the corresponding main pulley 35 to rotate. The movement of the piston plate 16 in the left block 13 pumps the air in the left block 13 through the fifth tube 46 into the passing block 47, and then enters the first tube 8, and is discharged through the sixth tube 48 and blown toward the printed packaging bottle, thereby increasing the air flow speed and drying the printing ink.

[0045] Then the reciprocating block 6 changes its movement direction again, drives the nozzle 7 to pass over the packaging bottle, and prints again, until the moving block 39 contacts the rack 15 at the right block 14 again, causing the clamped packaging bottle to rotate, and pumps air into the functional cylinder 24 again, causing the trigger block 26 to continue to move upward for a distance. After multiple printings are completed, the moving block 39 moves and contacts the rack 15 at the right block 14, and drives the clamped packaging bottle to rotate again. At this time, the trigger block 26 rises and contacts the delay switch 28, and triggers the delay switch 28, so that the solenoid valve 30 is energized. Under the elastic force of the second spring 27, the trigger block 26 is reset, and the electric clutch 34 is energized synchronously.

[0046] At this time, the reciprocating block 6 continues to change the direction of movement, and contacts the rack 15 of the left block 13 and pushes it, and the rack 15 drives the third gear 20 to rotate, and the rotation of the third gear 20 drives the main shaft 18 to rotate. Since the electric clutch 34 is energized at this time, the main shaft 18 will drive the corresponding main pulley 35 to rotate, and the main pulley 35 drives the secondary pulley 36 to rotate through the synchronous belt 37, and the rotation of the secondary pulley 36 drives the first tube 8 to rotate, so that the first gear 11 rotates, and due to the setting of the one-way bearing, the rotation of the first gear 11 cannot drive the second gear 12 to rotate. At this time, the rotation of the first tube 8 will drive the entire turntable 9 to rotate, so that the printed packaging bottle rotates away from under the nozzle 7, and the next packaging bottle rotates to under the nozzle 7 to wait for printing.

[0047] As the turntable 9 rotates, when the printed and air-dried packaging bottles rotate to the point where the conductive block 45 is separated from the conductive ring 44, the electric push rod 42 is powered off to release the clamping of the packaging bottles. At this time, the packaging bottles fall onto the guide block 49 and roll down along the guide block 49 for collection.
